I think you actually got the better ending with Norman, because even if you end up finding the killer, he'll find fame but also continue to suffer growing problems with the ARI/triptocaine deal.
You know there the Norman's Investigation there a circle that said "Investigate futher".WHY the fuck you didn't press it......you need to pay attention to that button, that could change the entire ending...............;p
Apparently if jayden is with you in the last scene you save prevent shelby from dying. Also there is a trophy for being a good villian with shelby. (Letting everyone die then having him escape). There are just a bunch of ways to play this game.
@ivan You weren't in control all the time, when you get close to the door the screen flashes to Manfred's body. They just skipped a little bit of time in that flash.
it also dosent explain this. When did shelby kill the clock guy. YOU WERE IN CONTROL OF HIM THAT ENTIRE TIME! you didnt kill him but it shows shelby killing him any way. Great lp and great game but one of the worse most unexplained endings of all time
